The issue you raise, is a known issue being tracked and worked on here

The issue I raise is that you should not make a change that makes life worse for all users. The feature is currently useless in 100 % of cases, so you should have rolled back immediately to the previous system as long as it works even in 0,1 % of the cases.

For now, I'm telling people to use the PediaPress book builder and ignore the PDFs produced by Wikimedia Foundation. This is not sustainable.
